title: [Use of enzyme test in chemotherapy of patients with cancer of the breast].
abstract: The activity of thymidine kinase, thymidine phosphorylase, adenosine deaminase, AMP 5'-nucleotidase was assessed in the serum of healthy females, patients with mastopathia cystica and those with stage IIIB breast cancer. The females age ranged from 23 to 70 years. The activity of the enzymes had significant differences in cancer patients. Minimal thymidine phosphorylase activity was found to suggest fibrous cancer. Changes in the enzymes levels in cancer patients on combined treatment may serve a biochemical test indicating the efficacy of the chemotherapy conducted.
